Home Depot rents a pressure washer for about $80 a day. Hiring a professional crew for a full house wash runs several hundred dollars. Math-wise, DIY sounds like a no-brainer. But math isn't the whole story. Here's an honest look at when DIY makes sense and when it doesn't.
When DIY Makes Sense
When You Should Call a Pro
The Hidden Costs of DIY
When people crunch the DIY math, they usually compare rental cost to service cost and stop there. Here's what they miss:
- Your time: A job we do in 4 hours takes a homeowner 8–12. What's a Saturday worth to you?
- Chemicals: Quality soft-wash solutions aren't at the hardware store. The "driveway cleaner" at Home Depot is a weak surfactant that won't touch algae.
- Mistakes: Etched concrete, stripped paint, damaged shingles, broken windows, injured backs. Any one of these wipes out the DIY savings ten times over.
- Insurance: If you damage a neighbor's property with overspray, your homeowner's insurance may not cover it. Ours does.
- Equipment gap: Consumer pressure washers max out around 2,000 PSI with cold water. Ours run 4,000+ PSI with hot water and surface cleaners. The results aren't comparable.
A Reasonable Middle Ground
Lots of our customers split the difference: they DIY the easy stuff — a back patio, a garbage enclosure, small sections of sidewalk — and hire us for the high-stakes jobs: the roof, the house, the main driveway, the pool deck. That's a totally rational approach, and we're happy to be the "pro for the hard stuff."
If You Do DIY, At Least Do This
Start with the lowest pressure setting. Hold the wand at least 18 inches from any surface. Never point it at windows, screens, shingles, or painted wood. Wear eye protection. Don't climb ladders with a pressure wand in hand. And test any cleaning solution on a hidden spot before committing. More homeowners have ruined their siding with "oxalic acid deck cleaner" than we can count.
If in doubt, call us. A free estimate costs nothing, and we'll tell you honestly whether the job is DIY-appropriate or not.
